EPA Regulation of Agricultural Biotechnology

No New Legislation for Biotech Products

How did EPA come to play a role in regulating genetically
engineered organisms? Were new statutes written for biotech?
History: How EPA Came to Play a Role in Oversight of Biotechnology
JUNE 2021 3
Date Event
1970’s Scientific advances in biology and genetics lead to early techniques of genetic engineering (GE)
1976 NIH Guidelines on research with recombinant DNA issued
1980 First GE product nears commercialization, raising question of how products should be regulated
1984 Federal Government workgroup determined existing statutes would be used
1986 Federal Government issues Coordinated Framework for Regulation of Biotechnology – use existing statutes administered by 3 agencies
Decision to Use Existing Statutes Led to Current Oversight Structure
Existing laws deemed adequate to address biotechnology products
Existing laws provided more immediate oversight
Existing laws provided more immediate regulatory certainty for developers, industry and the public
No alternative, unitary, statutory approach as the very broad spectrum of potential products cut across many product uses regulated by different agencies
Similar products would be regulated under a specific statute, e.g., pesticides regulated by EPA under pesticide authorities -> Product specific regulation
Agencies had experience with agricultural, pharmaceutical and other commercial products developed by traditional genetic modification techniques and thus possessed much of the expertise and experience needed to evaluate each product category

Today’s Regulatory StructureNo new biotechnology specific laws legislated by Congress
3 Federal agencies regulate biotechnology products under the Coordinated Framework for Regulation of Biotechnology (51 FR 23302)
◦ EPA◦ FDA◦ USDA
Using laws written prior to modern biotechnology◦ Product specific
Laws form jurisdictional network◦ Network assures reasonable safeguards for the public

Respective Agency Roles in Today’s StructureAgency Mission
FDA Determines whether foods/feed grown from crops modified by modern biotechnology are as safe as their conventional counterparts
FDA Considers genetic material engineered into an animal to be a new animal drug
USDA Responsible for protecting agriculture (plants and animals)from pests and disease
EPA OPP regulates use of pesticides
EPA OPPT regulates “new chemical substances” not regulated as foods, drugs, cosmetics, pesticides, tobacco, firearms; currently regulates intergeneric microorganisms –i.e, those combining genetic material from organisms in different taxonomic genera

What Biotech Products Does EPA Consider Pesticides?Genetically-engineered microbial pesticides
Pesticidal substance and genetic material necessary to produce it engineered into a plant◦ EPA regulates the PIP, not the plant
Pesticidal substance engineered into a mosquito (GE or microbial)

PIPs Can Occur Naturally in Plants, Be Moved into Plants By Breeding or Engineering

What is a PIP? Do PIPs only arise from genetic engineering?
What is a PIP? EPA considers a pesticidal substance that is intended to be produced and used in a living plant and the genetic material necessary to produce the pesticidal effect a pesticide
The Agency refers to this mixture as a “plant-incorporated protectant” or a “PIP”
• Under 40 CFR 174, a PIP is defined as a “pesticidal substance that is intended to be produced and used in a living plant, or in the produce thereof, and genetic material necessary for production of such a pesticidal substance...”
A PIP also includes any inert ingredient contained in the plant or produce thereof
• Any substance intended to confirm or ensure the presence of the active ingredient• For crop plants inert ingredients tend to be substances that can be used for “selecting” a plant line that contains the active ingredient, e.g.,
a substance conferring herbicide or antibiotic tolerance
Definitions can be found at Title 40 of the US Code of Federal Regulations at part 174.3

History: PIPs Regulatory Program DevelopmentYear Event1994 EPA issues proposed rule outlining EPA’s proposed program for PIPs
Describes proposed focus and scope of regulation1996 EPA begins registering PIPs under FIFRA, issuing tolerance exemptions under FFDCA 408
2001 EPA issues final rule implementing parts of 1994 proposal PIPs moved between sexually compatible crops through conventional breeding are exempted from FIFRA and FFDCA 408; other PIPs are subject to regulationNucleic acids exempted from FFDCA 408
2016- 2017 Coordinated Framework revisited and revisedNational Strategy for Modernizing the Regulatory System for Biotechnology Products issued
2020 EPA issues proposal to exempt certain PIPs derived from newer technologiesOver 34 currently registered PIP active ingredientsOver 138 PIP product registrations

Examples of PIPs Currently RegisteredFunction Type of Product That Could Be a PIP
Insecticide Plant-produced protein that is toxic to insects eating a plant part, e.g., to a caterpillar
Insecticide Plant-produced double stranded ribonucleic acid (dsRNA) that is toxic to insects eating a plant part, e.g., to a beetle larva (RNAi product)
Fungicide Plant-produced substance that prevents fungal growth, e.g., R gene
Virucide Plant-produced genetic material that triggers the plant to respond to an infecting virus by chopping up the virus’ genetic material, e.g., dsRNA (RNAi product)

Biotech Plants: Which Agency Regulates?
Product Function EPA regulates USDA regulates FDA oversees
MON-87411-9 Corn variety engineered to express insecticidal dsRNA against corn rootworm
The PIP and any residues in food/feed
The plant if plant pest risk Food or feed
ARS-PLMC5-6 Plum variety engineered to be resistant to plum pox virus
The PIP, and any residues in food/feed
The plant if plant pest risk Food or feed
DAS-81910-7 Cotton variety engineered to be tolerant to glufosinateand 2,4-D
No EPA regulation of the DAS-81910-7, but EPA regulation of the herbicides used, and any herbicide residues in food or feed
The plant if plant pest risk Food or feed
OKA-NB001-8 Apple variety engineered to reduce browning
No EPA regulation The plant if plant pest risk Food or feed

Interagency CoordinationThe 1986 Coordinated Framework recognized the need for coordination between the regulatory agencies
EPA works with FDA and USDA to ensure that products of modern biotechnology are safe
◦ Through various working groups◦ Through communications between agency scientists
Recently, EPA, FDA and USDA issued an Update to the Coordinated Framework and a National Strategy for Modernizing the Regulatory System for Biotechnology Products
◦ These documents clarify current roles and responsibilities of the 3 agencies and identify future steps to ensure the regulatory system addresses novel types of products developed through advances in science and technology

Single Ag Biotech Contact Point
Agencies established a single point of contact to help facilitate developer interactions with relevant agencies
Created a landing page hosted by USDA that provides general information on the federal regulatory system for biotechnology products, as well as specific points of contact and/or links for submitting questions to regulatory agencies
Provides links to landing page for each agency’s website
